<pre>I think the level of importance of this bug should be changed from
"enhancement" to "major". Here is my rationale:
- The bug has not been addressed in 8 years; worse: it has remained in status
"NEW" for 8 years!
- Nowadays, all the consumer-grade CPU vendors have split their CPUs' power in
several slower cores rather than single faster ones.
This makes Calc barely usable in a professional environment with heavy
calculation loads. I do my best to push everyone towards open source software,
with some success, but in the case of Calc, it's becoming ridiculous.
In an environment where everybody has 8 core CPUs, my colleagues can launch
heavy tasks (like 300,000 rows, each with a lookup in a 25,000 table) and have
the result in about 20 minutes in Excel, while I have to wait 3 hours for the
same thing (with LibreOffice 7 in Debian and the same hardware). I actually
came to learn R just to avoid re-creating a Windows partition dedicated to
Excel use on my computer.
Therefore, I believe that to be an Excel challenger taken seriously in the
multicore-friendly XXIst century, Calc not being able to make use of those
multicore CPUs is a major bug.
Note: Activating "Settings > Calc > Calculation > multi-thread" has no effect
and enabling OpenCL is not persistent after LibreOffice required restart.</pre>
